I am a stake administrator and created a calendar to be used to schedule events such as weddings, etc. one building in the stake. I assigned one editor and all was going well, but recently, the events that are entered show 2 hours different when I view the events. However, on the editors computer, the times are correct. I have checked the time zone and all is correct. Not sure what to do.

You said "zone" in the singular. There are three time zone settings that could potentially affect this issue: the time zone for the location (building), and the time zone on both your computer and the editor's computer. I'd double check all three of those settings, and also take a look at the times on another computer. That will help you narrow down which one is wrong.

Questions that can benefit the larger community should be asked in a public forum, not a private message.
